This is a book about real-world design techniques for analog circuits: amplifiers, filters, injection-locked oscillators, phase-locked loops, transimpedance amplifiers, group delay correction circuits, notch filters, and spectrum regrowth in digital radio frequency (RF) transmitters, etc.
The book offers practical solutions to analog and RF problems, helping the reader to achieve high-performance circuit and system design. A variety of issues are covered, such as:
How to flatten group delay of filters
How to use reciprocity to advantage
How to neutralize a parasitic capacitance
How to deepen a notch by adding only two components to the network
How to demodulate a signal using the secant waveform and its benefit
How to flatten the frequency response of a diode detector
When to use a transimpedance amplifier and how to maximize its performance
How to recover non-return-to-zero (NRZ) data when alternating current (AC) coupling is required
Why phase noise corrupts adjacent communication channels
Simple method to prevent false locking in phase-locked loops
How to improve the bandwidth of amplification by using current conveyors
A very simple impedance matching technique requiring only one reactive component
How to use optimization
Quadrature distortion and cross-rail interference
This book is meant to be a handbook (or a supplemental textbook) for students and practitioners in the design of analog and RF circuitry with primary emphasis on practical albeit sometimes unorthodox circuit realizations. Equations and behavioral simulations result in an abundance of illustrations, following a "words and pictures" easy-to-understand approach. Teachers will find the book an important supplement to a standard analog and RF course, or it may stand alone as a textbook. Working engineers may find it useful as a handbook by bookmarking some of the step-by-step procedures, e.g., the section on simplified impedance matching or group delay flattening.
